following is a specication.

The present invention relates to vmeansl which is so selected that it will balance the weight of the sash `and window. in any of the lpositions thereof.

A further object of the invention `is vthe provision of a means automatically operated by the movements of the sash to bal-` ance the same.

These and other objects of my invention lwill become more fully apparent as thedefscription thereor1 proceeds, and will then be `more specically pointed 'out in the appended claims. v i

.In the accompanying drawing, forming a material part of this specification- Figure 1 is a top plan view of a window frame andsash equipped with a device constructed according to the present invention.

Figure 2 is a side elevation thereof partly in section. l

A windowframevv 10\ has 'a chamber 1l formed therein, and in this chamber upper sockets 12, 13, and lower sockets 14, 15 are provided in which the vcorrespondingly Ashaped upper and lower ends of. vertical v rods 16 and 17 'are rotatablyheld. The rod 16 intermediate its ends is formed witha vthickened part 18 providedwith an outer spiral groove 19 adapted to be engaged by a ridge of the spirally grooved inner face of a sleeve 20 provided with a lateral tongue 21 engaging withy its outer end a recess 22 of a metal socket 23 within the lower bar vof the window sash 24. Between its upper en'd and the thicker part of rod 16the same carries `a gear wheelV 25 in mesh witha gear j 1 said. sockets, a thickened part on one of said wheel 26 on rod 17. r

`Between gear wheel 26 and the bottom wall of chamber 11 arstrong spiral spring 27 is wound around the rod 17 fastened with,
